Abstract (en)
A 6-high cold rolling mill. The mill is of the type having free floating, side-supported upper and lower work rolls, chock mounted upper and lower intermediate rolls and upper and lower back up rolls. Vertically acting hydraulic cylinders are provided for intermediate roll balancing, bending, counterbalancing and vertically shifting the upper and lower intermediate rolls toward and away from each other. Horizontal cylinders provide axial shifting of the intermediate rolls and two cylinder actuated supports are provided to lift the upper work roll. All of these cylinders are mounted on the mill housing and no hydraulic disconnection and reconnection is required for replacement of the intermediate rolls and/or the work rolls. Each intermediate roll assembly supports between its chocks a pair of side support assemblies for the work rolls. Lubrication to the intermediate roll chocks and side support assemblies is made by spring loaded lubrication connections mounted on the front and rear doors of the mill housing. Movement of the upper and lower intermediate roll chocks away from each other automatically disconnects the lubrication connections from the chocks. Movement of the upper and lower intermediate roll chocks toward each other automatically reconnects the lubrication connections to the chocks. <IMAGE>
